It more like the tuning capacitor(s) that is connected to the HOT that is defective or a cristalized/dry solder joint nearby the flyback transformer.

Sound but no picture on sonny trinitron


Check and replace damaged component/s at its horizontal scan output section circuit. Check the LOT (Line Output Transformer) too for damage. Replace the horizontal scan output transistor. Check the input voltage to LOT. If the voltage is absent check the feeder resistor; if any. If you wish to get some details; check the site linked here. Pull up older posts.

Check its horizontal output section circuit for fault. Check the horizontal output transistor. If it found leaky, suspect horizontal output transformer.

The picture on my Sony is shaped like an hour glass


There is an apparatus on the back of your picture tube called a yoke.This distributes your picture on your pic tube uniformly.If this or the circuits enabling it malfunction,then you will get distortion-namely an hour glass shape.Tv has to be trouble shooted.

I have a Sony Trinitron 34" tv. It will not turn on. The red light blinks 6 times then pauses and blinks 6 times again. Is this an easy fix or time to get a new t.v.?


hi,
ur tv has problem with horizontal output stage. check the horizontal output transistor. if it found short replace the same and switch on the tv. if the same fault occur again, then the lot (line output transformer) may be faulty. also check for any dry soldering in the power supply stage and horizontal output sage.
ok

My sony trinitron 32" tv just went black and the


Hello

Six blinks of standby light in Sony TVs denotes the absence of horizontal oscillation.

No Horizontal (H STOP), no raster, goes to the blinking self-diagnosis function immediately. Check C515 & 516 and the jungle IC, IC206.
In most cases the Ic is foud defective. anyway check its soldering points for any loose contact, or bad solerings. Check the line drive transformer, a very little transformer soldered directly to the main printed circuit board, very close to the horizontal output transistor. Check its primary winidngs for open. If it gets open no horizontal drive signal will be present at the base of the horizontal output transitor, that also may the cause of horizontal stop.

Picture shaped like hour glass


You have a PIN CUSHION problem, is usually a bad capacitor or open resistor in the above cicuit. Check all the caps around the horizontal output transister for ESR leakage.

The picture is convexed,or hour glass.


Sounds like problem in B+ voltage line to horizontal output transistor. Possible bad filter capacitor or leaky diode in power supply.
